The result is confusion in the guest OS. The current DRM drivers in upstream Linux seem to default to VESA modes. These are either provided by qemu, or Xorg uses a fixed internal list. As a result the VM window is 1280x960. Much too large for my native display. It seems qemu does not provide a virtual display with valid EDID data. If it would start doing that, the host admin could force a certain display size. Ideally also with proper DPI data. Any idea if thats possible to implement? Olaf
